Blissey

Colossal base HP, high base Special Defense, and only one weakness make Blissey the premier special wall in UU, and thanks to its access to various support moves such as Wish and Heal Bell, Blissey finds itself a staple on stall teams. Furthermore, Blissey's ability Natural Cure in combination with reliable recovery in Soft-Boiled makes it very hard to wear down. However, despite access to Seismic Toss and Toxic, Blissey is quite passive, and as a result, it is shut down by Taunt users, such as Krookodile and Gengar. Blissey is also used as a setup fodder by Steel-types such as Scizor and Cobalion, which are immune to Toxic, and bulky Substitute users, such as Suicune. In addition, a poor Defense stat means that Blissey is vulnerable to the most physical attackers in the tier, such as Mega Sharpedo and Terrakion. Overall, although Blissey is a reliable staple on Stall teams, it finds itself hard to fit onto playstyles other than stall and balance, and as a result, it is mostly restricted to them.
